Twins first baseman Justin Morneau has missed the team's last two games, but isn't worried about his back. Morneau said Thursday morning he "tweaked" his back on the first swing of his last at-bat Tuesday night and insisted the injury is unrelated to the back issue that led to him missing the final few weeks of last season. "Hopefully I'll be good to go tomorrow," Morneau said. "I don't know, we'll see how it goes tomorrow when I get to the field and start swinging and stuff. Felt better yesterday than I thought it was going to when I woke up. Today, even better."
